过早或过晚地收获农作物,对产量和品质都会造成一定的影响。收获过早,籽粒尚未充分成熟,这样既会降低籽粒品质,又会减少粒重,降低产量;相反,则造成籽粒脱落在地,减少收成,因此,要做到增产丰收,就必须要掌握各种农作物的最佳收获期,以防伤镰和落镰而影响增产。现介绍几种主要农作物的最佳收获期及识别方法。 Harvesting crops too early or too late can have some impact on yield and quality. Premature harvest, the grain has not yet fully mature, which will not only reduce the grain quality, but also reduce the grain weight and reduce the yield; the opposite, then cause the grain fall to the ground, reduce the harvest, so to achieve yield increase, we must grasp the The best harvest of crops, to prevent sickle and sickle sickle yield. Here are some of the main crop of the best harvest and identification methods.
